Proposal: Benchmarking performance and stability #34

Closed vielmetti closed 7 years ago

vielmetti commented 7 years ago

The benchmark tools at https://github.com/networknt/microservices-framework-benchmark provides a common "microservices" framework for testing and characterizing performance across systems; it would be useful to set something up for this.

The benchmark provided is a simple "Hello world" fetch, which is simple to implement.

Expected Behavior

Performance of FaaS is well-characterized.

Current Behavior

Performance of FaaS seems to be good, but there aren't numbers.

Possible Solution

Do some simple load testing, and characterize performance, prior to running a benchmark.

Context

The "microservices" list has a lot of interesting projects in it which is worthwhile to review in any case.

I have done something similar with go bench - but since it runs in a way non-determinsitically it seemed hard to do repeat runs. Is this something you'd like to experiment with @vielmetti ?

vielmetti commented 7 years ago

I'm looking at ab (apache benchmark) if I can set it up correctly, since it seems to have some good repeated testing and measurement.

By all means play with ab, but I've had mixed results with Docker swarm in the past due to the way it keeps connections alive etc.

Happy to re-open the issue if you find some more time for testing @vielmetti

I hear Gattling is really good for ramping up tests.
